Ofgem has announced a 13% increase in Britain’s household energy price cap from July after soaring wholesale energy costs linked to the US-Israel conflict with Iran pushed global oil and gas prices sharply higher.
The increase means a typical household in England, Scotland, and Wales will pay approximately £221 more annually for gas and electricity under variable tariffs, as disruption to the Strait of Hormuz begins feeding directly into consumer energy bills.
Officials and energy suppliers have warned that prices could rise even further during winter if the conflict continues disrupting global energy supply chains and wholesale gas markets.
Key Overview
- Ofgem raised the UK energy price cap by 13%
- Typical annual household bills will rise to £1,862
- Households face an average increase of £221 annually
- The rise takes effect from July to September 2026
- The Iran war triggered major global energy market disruption
- Gas bills will rise by 24% while electricity increases by 5%
- Around 40% of households on fixed tariffs are unaffected
- The Strait of Hormuz blockade disrupted global oil and gas flows
UK Energy Bills Rise as Iran War Hits Markets
Ofgem has increased Britain’s household energy price cap by 13% after soaring wholesale energy costs linked to the US-Israel conflict with Iran pushed global oil and gas prices sharply higher.
The new cap means a household using a typical amount of gas and electricity will pay approximately £1,862 annually from July, an increase of £221 compared with the previous cap period.
The revised price cap applies to millions of homes across England, Scotland, and Wales that remain on variable energy tariffs.
Analysts say this marks the first major direct impact of the Iran conflict on British household energy bills since the war began in late February.
The new cap will apply from July 1 through September 30.
Strait of Hormuz Crisis Drives Energy Shock
The increase follows major disruption to global energy markets caused by the conflict involving the United States, Israel, and Iran.
Energy prices surged after Iran responded to military strikes by effectively blocking the Strait of Hormuz, one of the world’s most strategically important energy shipping routes.
Approximately one-fifth of global oil and gas trade normally passes through the narrow waterway.
Analysts say the disruption created one of the largest global energy supply shocks in recent history.
Oil prices have risen sharply since the conflict began, with Brent crude climbing to around $98 per barrel after increasing by more than one-third.
The resulting spike in wholesale gas prices has now started feeding directly into household electricity and heating bills across Britain.
According to Ofgem, wholesale energy costs account for approximately 40% of a household energy bill.
Households Face Higher Gas and Electricity Costs
Under the new price cap, households will experience significantly higher gas costs alongside smaller increases in electricity charges.
Ofgem said gas bills will rise by approximately 24%, while electricity bills will increase by around 5%.
The regulator increased the annual cap from £1,641 to £1,862 for a typical dual-fuel household paying by direct debit.
That equates to roughly £18 extra per month for average households.
However, analysts note that the actual increase may feel larger for many consumers because Ofgem also revised its estimates for typical household energy consumption downward.
The regulator reduced its estimate for typical usage to:
Previously, Ofgem’s estimate stood at:
- 11,500 kWh of gas annually
- 2,700 kWh of electricity annually
Critics say the revised usage assumptions may partially mask the scale of the underlying price increase because consumers will still pay substantially more per unit of energy.
Millions Shielded by Fixed Tariffs
Not all households will be immediately affected by the price cap increase.
According to Ofgem, approximately 40% of accounts — around 22 million households — are currently on fixed tariffs.
Those households will not see immediate bill changes until their fixed-term contracts expire.
The energy price cap only applies to customers on default or variable tariffs.
Analysts say many consumers shifted toward fixed deals during recent years following repeated energy market volatility and previous energy crises.
However, millions of households remain exposed to fluctuating wholesale prices through variable-rate contracts.

Government Warns of Further Winter Pressure
British officials warned that energy costs could rise even further during autumn and winter if the conflict in the Middle East continues.
Several energy suppliers have forecast additional increases later this year because colder weather typically raises gas demand significantly.
UK Energy Secretary Ed Miliband described the latest increase as deeply concerning for households already facing financial pressure.
“The rise in the price cap because of a war we did not choose is deeply unwelcome news for households across the country,” Miliband said.
“We know people were under pressure before this crisis, and that’s why easing that burden is our number one priority,” he added.
The UK government said it is currently working on targeted support measures for vulnerable households if energy costs remain elevated into winter.
Analysts say governments across Europe are increasingly under pressure to shield consumers from prolonged energy price volatility linked to geopolitical conflicts.
Previous Bill Relief Reversed
The sharp increase comes only months after British households experienced temporary relief from lower energy bills.
Energy costs fell by approximately 7% between April and July after government measures reduced certain charges and levies applied to household bills.
That earlier reduction occurred shortly before the outbreak of the Iran conflict.
Chancellor Rachel Reeves had previously removed green levies from household energy bills, helping reduce costs temporarily.
However, the subsequent surge in wholesale gas prices caused by the Middle East conflict has now reversed much of that relief.
Analysts say global fossil fuel market volatility continues exposing households to geopolitical risks and international supply disruptions.
Europe Faces Broader Energy Security Concerns
The latest UK price increase reflects broader energy security concerns across Europe following the Strait of Hormuz disruption.
Many European economies remain heavily dependent on imported natural gas and oil despite growing investment in renewable energy.
Analysts say the current crisis is likely to accelerate political pressure for faster deployment of renewable energy, battery storage, nuclear power, and electrified heating systems.
The conflict has also renewed debate about Europe’s vulnerability to global fossil fuel supply disruptions.
Several governments are already discussing additional measures aimed at improving domestic energy resilience and reducing dependence on imported hydrocarbons.
Outlook
Ofgem’s decision to raise Britain’s household energy price cap highlights how quickly geopolitical conflicts can ripple through global energy markets and impact consumers directly.
The 13% increase reflects the growing economic consequences of the Iran conflict and disruption to the Strait of Hormuz, one of the world’s most important energy supply routes.
For households, the rise adds further pressure to already elevated living costs while raising concerns about even higher winter bills if global energy markets remain unstable.
At the same time, the crisis is likely to strengthen calls for faster investment in renewable energy and greater long-term energy security across Europe.
